R Notes

Introduction

Welcome to Brad Cannell’s R Notes!

This repository is for a Quarto version Brad Cannell’s R Notes. This repository is primarily intended to be helpful to me, but even better if you find it useful too! This version of my R Notes replaces the previous Bookdown version.

Why am I doing this (as opposed to just keeping notes locally)?

• Better organized (e.g., chapter structure and search).

• Easy access – just click on the bookmark on web browser.

• Practice using Quarto.

• Might help with R4Epi – This can be sort of a sandbox for developing before I add things to R4Epi.

Organization

These notes are loosely organized into the following parts:

• Programming: Notes about optimizing code, writing functions, creating packages, and repeated operations.

• Data Simulation: Notes about simulating data.

• Working with external files: Notes about things like data transfer, web scraping, PDF scraping, and using Officer to scrape Microsoft Office documents.

• Data management: Notes about manipulating/transforming/filtering data that is already in R.

• Analysis: Notes about creating numerical summaries of data.

• Data visualization: Notes about graphical summaries of data. A lot of this will be about ggplot.

• Presenting results: Notes about making numerical and graphical summaries accessible outside of R. This can include webpages, static dashboards, PDF documents, Microsoft Office documents, etc. This does not include Shiny apps.

• Collaboration: Notes about collaborative coding. This is primarily notes on using Git and GitHub.

• Shiny: I am no longer keeping notes about Shiny here. Shiny has it’s own notebook. https://brad-cannell.github.io/shiny_notes_quarto/
